Benefits of technology

The present invention provides a treatment apparatus for workpieces that can be moved in a controlled and safe manner within the apparatus and during the transfer from one level to the next level. The apparatus has multiple receiving chambers and an outlet opening, and a transfer apparatus for moving the workpieces from the outlet opening to the inlet opening. The treatment apparatus makes it possible to even heavy workpieces with sensitive surfaces to be moved without damage. The workpieces can be moved through an angle of at least approximately 90° and all of the receiving chambers rotate synchronously with one another. The apparatus can also have a lock function for separating the receiving chambers from the environment and adapting them to a new ambient state. The technical effects of the invention include improved treatment efficiency, reduced damage to workpieces, and improved safety during the transfer process.

Problems solved by technology

Particularly in the case of heavier workpieces having a surface that should not be damaged, an uncontrolled drop from one level to another level of the treatment apparatus does however present a considerable risk.

second embodiment

[0170]In the treatment apparatus 100 illustrated in FIG. 13, the workpieces 102 passing through the treatment apparatus 100 are in at least one receiving chamber 126 not deposited onto stationary spacers 176 but received in a workpiece support 226, which is rotatable about an axis of rotation 228 that is aligned radially relative to the axis of rotation 114 of the chamber drum 112.

[0171]Rotation about the axis of rotation 228 is effected in said case by means of a rotary shaft 230, which is fastened to a radially inner end wall 232 of the workpiece support 226 and supported rotatably on the hollow shaft 118 of the chamber drum 112.

[0172]An end of the rotary shaft 230 situated inside the hollow shaft 118 is provided with a bevel gear 234, which is in mesh with a stationary central bevel gear 236, which is aligned coaxially with the axis of rotation 114 of the chamber drum 112 and connected to the upper side of the base plate 106 of the housing 104 of the treatment apparatus 100 by a ...

third embodiment

[0182]Otherwise, a treatment apparatus 100 corresponds in construction and function to the first implementation function, to the above description of which reference is made in said regard.

fourth embodiment

[0183]In a treatment apparatus 100 illustrated in FIG. 15, at least one level of the treatment apparatus 100 has the function of a vacuum lock.

[0184]In the embodiment illustrated in FIG. 15, the relevant chamber level 128 is provided with sixteen receiving chambers 126, which because of the rotational movement of the chamber drum 112 about the axis of rotation 114 are moved from the inlet opening 138 of the chamber level 128, by which the chamber level 128 is in communication with the ambient atmosphere and through which the workpieces 102 are introduced into the chamber level 128, to the outlet opening 142 of the chamber level 128, which lies at an angular distance of 180° opposite the inlet opening 138 and at which the vacuum ultimate pressure of the chamber level 128 is reached and by which the chamber level 128 is connected to a following chamber level 128 that is likewise at least partially under vacuum.

[0185]Because of the rotational movement of the chamber drum 112, the recei...

Abstract

In order to provide a treatment apparatus for treating workpieces or groups of workpieces that are conveyed from an inlet to an outlet of the treatment apparatus, wherein the treatment apparatus comprises a plurality of treatment levels and with said treatment apparatus the workpieces to be treated are passed from level to level in a safe and controlled manner, it is proposed that the treatment apparatus comprises a housing and receiving chambers, which rotate relative to the housing, for receiving the workpieces or groups of workpieces, wherein the receiving chambers are disposed in at least two different chamber levels and an outlet opening in the housing is associated with a first chamber level, through which the workpieces or groups of workpieces travel first, and an inlet opening is associated with a second chamber level, through which the workpieces or groups of workpieces travel after the first chamber level, and wherein the treatment apparatus comprises at least one transfer apparatus, which moves the workpieces or groups of workpieces from the outlet opening to the inlet opening.

Description

RELATED APPLICATION[0001]The present disclosure refers to the subject matter that was disclosed in German patent application No. 10 2004 015 5.6 of 30 Mar. 2004. The entire description of this earlier application is incorporated by reference in the present description (“incorporation by reference”).FIELD OF THE DISCLOSURE[0002]The present invention relates to a treatment apparatus for treating workpieces or groups of workpieces that are conveyed from an inlet to an outlet of the treatment apparatus.BACKGROUND[0003]Such an apparatus is known, for example, from DE 44 42 152 A1.[0004]In the treatment apparatus known from DE 44 42 152 A1, the parts to be treated are fed to so-called “virtual chambers” and in these virtual chambers are conveyed through processing treatments. This treatment apparatus comprises a plurality of circular bases disposed with spacing one above the other, which are enclosed by a wall cylinder and between which there is in each case a system of blades disposed at...
